A rectangular squeeze film bearing will be used to absorb intermittent loads. The bearing is 500mm wide. The initial gap between

the bearing plates is 2mm. The applied load is 50N. Oil viscosity 1000 mPa-s. a) If the bearing gap should change to 1mm in 0.5s, how long will you make the bearing? b) Using your calculated length, how long will it take to move if the viscosity is changed to 300 mPa-s?

A variação no comprimento de uma barra de alumínio foi de 0,0002m. Calcular a variação na temperatura a =22x10-⁶
Furkat [3]

Answer:

1.82°C

Explanation:

presumir inicial comprimento = l₀ = 5 m

dado que:

coeficiente de expansão (α) = 22 x 10⁻⁶, A variação no comprimento (ΔL) = 0.0002 m,

inicial comprimento = l₀ = 5 m

variação na temperatura = ΔT

para Calcular a variação na temperatura,  nós usamos a fórmula:

\Delta L=l_0\alpha \Delta T

substituindo valores:

0.0002=5*22*10^{-6}\Delta T\\\Delta T=\frac{0.0002}{5*22*10^{-6}}\\ 5*22*10^{-6}=1.82^0C

variação na temperatura = 1.82°C

Which statements describe how a machine can help make work easier? Select two options.
ad-work [718]

Answer:

  • It can put out more force than the input force by decreasing the distance through which force is applied.
  • It can apply a force to an object in a different direction than the force applied to the machine.

Explanation:

Assuming the machine is a simple machine, such as a lever or pulley, the machine will not do any more work than is put into it. However, it can change the magnitude or direction (or both) of the input force required to achieve a particular output force.

Because the machine does not increase the work done, if the output force is greater, the output distance must be less.

The applicable observations are ...

  • It can put out more force than the input force by decreasing the distance through which force is applied.
  • It can apply a force to an object in a different direction than the force applied to the machine.
